DU1 – Tagaytay – Jan 2017

During this visit I had more time to setup my station in Tagytay and test the antennas. I was very impressed by the performance of the spider beam  and even the good propagation on the lower bands.

Spider beam for 20, 17 and 15 m and trap dipole for 40 and 80 m

On 1st of Feb I went to NTC and PARA office to take the exam for class A Philippine Amateur radio license. Hopefully I will receive my DU1 callsign soon.

DU1- Dasmariñas – Aug 2016

This time we stay longer than a week in our second home, and I set up a 12 m fibreglass pole with a G5RV multi-band dipole antenna for 40 m to 10 m. The pole is located at on corner of our area, the dipole endings are fixed at two other corners, so the antenna has a form of a 90 degree inverted vee.

The antenna analyser shows clearly 3 resonant frequency points: around 40 m, 20 m and 10 m. All resonances seem to be below the amateur radio frequency bands, probably because of the inverted vee form.

Using my “old” AT-130 antenna tuner, I can operate on all bands from 40 m to 10 m including the WARC bands.
